The first target of the James Webb Space Telescope is a sun-like star in the Great Bear constellation, but it is just to check the mirrors are properly aligned.
The $10 billion telescope is months from being ready to begin operations, despite arriving at its final orbit on January 24, as it has to cool down and undergo weeks of calibration work, to ensure the 18 segments of the main mirror 'work as one'.
After reaching its orbit, at the second Lagrange point (L2), an area of balance between gravitational forces of the Earth and the sun, NASA revealed its first target.
